Late as Yetu was, the wajinru must be starving for it, consumed with desire for the past that made and defined them. Living without detailed, long-term memories allowed for spontaneity and lack of regret, but after a certain amount of time had passed, they needed more.

It was enough that their bodies retained a sense memory of the past, which could sustain them through the year until the next Remembrance.
